Abstract

We present here a rapid immunochromatographic assay for the detection of Middle East respiratory syndrome coronavirus (MERS-CoV) antigen in the nasal swabs of dromedary camels. The assay is based on the detection of MERS-CoV nucleocapsid protein in a short time frame using highly selective monoclonal antibodies at room temperature. The relative sensitivity and specificity of the assay were found to be 93.90% and 100%, respectively, compared to that of the UpE and open reading frame 1A (Orf1A) real-time reverse transcriptase PCR (RT-PCR). The results suggest that the assay developed here is a useful tool for the rapid diagnosis and epidemiological surveillance of MERS-CoV infection in dromedary camels.

摘要

我们在此展示一种快速免疫层析检测法,用于检测单峰骆驼鼻拭子中的中东呼吸综合征冠状病毒(MERS-CoV)抗原。该检测法基于在室温下使用高选择性单克隆抗体在短时间内检测MERS-CoV核衣壳蛋白。与UpE和开放阅读框1A(Orf1A)实时逆转录聚合酶链反应(RT-PCR)相比,该检测法的相对灵敏度和特异性分别为93.90%和100%。结果表明,此处开发的检测法是用于快速诊断和流行病学监测单峰骆驼中MERS-CoV感染的有用工具。
